No. They didn't have a coffee pot in the Mermaid rooms. We've stayed in Mermaid (Ariel) and Cars (C). Others can say what they want, but it is a long walk to the busses and to grab some coffee or a late evening snack. Cars was close. We loved Cars so much better. I think it's a much better choice then Lion King because of the courtyard and pool. Lion King doesn't have a pool.
I would even choose Cars over Nemo. The atmosphere around the Cars suites is so unique.
The beds do leave a lot to be desired, but they are not horrible.
Noise level in both Mermaid and Cars was pretty significant, but once everyone finally gets into bed it's fine the rest of the night in Cars. Not true in Mermaid. We heard toilets flushing and other bathroom noises all night. The only time it was a little quiet was when the air conditioning unit was on. When it went off, it would get warm quickly and the noise would be bothersome. The layout in the Cars Suites, makes for a quieter night.
None of this would stop us from staying there again if the price is right. We got Mermaid, the first week it was open, for 97 during the week and 119 on the weekend. I know it's more now.
